This application relates to timing devices primarily designed for the purpose of timing the parking of vehicles.

Devices for timing the parking of vehicles have heretofore been designed for operation in various ways.. For example, some of the prior art devices are adapted to be operated by pressure applied to a given portion of the device by a vehicle parked in the designated area. Others are adapted to be started and stopped manually by the operator of the vehicle. Y Still others are adapted to be started manually and stopped automatically after a given length of time has expired. It is an object of this invention to provide a device which is adapted to be started by the operator of the vehicle at the time the same is parked, to provide a clear indication at all times of the amount of time the vehicle has been parked, and to provide a clearly visible signal adapted to be actuated when the vehicle has been parked a predetermined length of time.

It is a further object to provide a coin control for this type of mechanism.

It is a further object to provide a mecha nism of this type which is actuated by a'spring powered clock mechanism, and to provide for the rewinding of said mechanism upon the manual operation of the coin controlled starting device.

It is a further object to provide a device of this type having a coin controlled means for resetting the indicating mechanism, and for simultaneously rewinding the power producing unit.

It is a further object to provide a device of this character in which the clock mechanism can- 35 not be stopped within a predetermined period without access to the interior of a housing in which it is mounted.

Other objects and advantages of this invention will become apparent from the following description and the accompanying drawings taken with the appended claims. It is to be understood, however, that the particular embodiment set forth in the following description and the ac- 45 companying drawings is by way of illustration only, and is not to be construed as a limitation on this invention. This invention is to be limited only by the prior art and by the terms of the appended claims.

Referring more in detail to the structure shown, (see Figures 14, 15 and 16) the mechanism of this invention is mounted within a housing having an upper portion I for receiving the mechanism proper, a lower portion 2 within which the coins that have been placed in the device are collected, and a lower end portion 3 of a size to I lit within the vertical tubular support 4. This tubular support 4 is in turn mounted on a base 5 or may be secured in vertical position by any other desirable means. It is to be understood that the housing containing the mechanism may forming the external portion of the manual operating mechanism may project. Directly above the opening I is a slot i0 adapted to receive a coin for controlling the action of the knob 9.

Formed in the front wall .of the part 2 are two round windows II and i2. The window II is for the purpose of enabling an observer to see the last coin which has been placed in the device. said coin to be held before this window in a manner which will be presently described. The window I2 is for the purpose of enabling an observer to see at a glance whether or not the coin receiving box or bank is in its proper place within the housing.

The rear wall of the portion I (see also Figure 4) is formed with a door I 3 hinged adjacent its lower edge at II, and provided with panels I! and I6 corresponding respectively to the panels 8 and l in the front wall. A suitable lock I1 is provided adjacent the upper edge of the door l3 for the purpose of preventing unauthorized tampering with the mechanism.

Mounted in the rear wall of the portion 2 'of the housing is a second door i8 hinged adjacent its lower edge as at l9, and provided with a window at 20, and a lock 2|. This door It is for the purpose of providing access to the coin receiving box, and the window which is'directly opposite the window I 2 in the front wall of the housing when the door It is closed is for the purpose of enabling an observer to tell deflnitely at a glance whether or not the coin receiving box is place.

The mechan m is mounted within the portion I of the housing by means'such as screws 22 which pass through a front plate 23 forming a portion of the mechanism frame. This front plate 23 is connected by means of posts 24 to a rear plate 25. Mounted on the front of the plate 23 and in alignment with the window 1 of the housing is a dial 26 (see Figures 1 and 2). Two of the posts 2| are provided with rearward extensions 21 on which is mounted a plate 23 carrying a second dial 29 in alignment with the window It in the door iii in the rear of the housing.

Mounted on the rear of the plate is a clock work mechanism mounted in a suitable frame, said frame comprising a front plate 30 which is secured directly to the rear of the plate 25, rearwardly extending posts 3], and a rear plate 32.

An arm 33 (see Figures 4, 5 and 11) is mounted behind the plate 23 on the axis of the knob 9, and is keyed to this axis by means of a pin 34. This arm 33 is normally held in its vertical position directly behind the coin slot I in the housing by means of a spring 35 anchored at one end to the plate 23 by a screw 31, and at the other end to the arm 33 by means such as a screw 3. The rotational movement of this arm 33 about the axis of the knob S'is limited by means of stops 38 and 39 shown in Fig. 10.

The arm '33 is formed with a slot 40 in a longitudinal plane, said slot being so positioned as to be in direct alignment with the slot l I in the housing when the arm 33 is in its vertical posi tion as illustrated in Figs. 10 and 11. In this position it is apparent that it will receive a coin ll passed through said slot, and that the rear edge ofsaidcoinwillrestagainstanangleshaped member 42 which embraces the rear portion of the arm 33. Projecting rearwardly from this member 42 are a pair of pins 43 and 34, the purpose of-which will presently be described. The channel shaped member 42 is held in its proper position by means of screws 4' passing through 'a portion of the arm33, and having a portion surrounded by springs 30 disposed within recesses in the opposite face of the arm 33. The screws 4! are provided with heads 41, and it will be seen that the springs I will constantly urge the screws 45 in such a direction as to hold the channel shaped member 42 against and in embracing relation with respect to the arm 33.

Secured to the rear face of the plate 23 by means of screws 43 is a track 49 having a beveled end 50 (seeFiguresfiand 6),thistracklyingin the path of the coin II as it is moved around by the turning of the knob 9 and the arm 33. It will be seen that as the coin rides up on the beveled end 53 of the track 43 it will force the channel shaped member 42 outwardly away from the arm 33, and will hold it in that position as the coin rides along the surface of the track it. Disposed at intervals along this track 43 are small projections 5| forming ratchet teeth over which the coin 4| will ride in the forward direction of movement, but if the knob 3 be released, the coin ll will be caught by the last of these projections over which it has passed, and the knob 9 will be prevented from returning to its original position. Extending in a circular path substantially parallel to the track 49 (see Figure 10), andradially outwardly therefrom, is a shield or retaining member 52 adapted to prevent the coin II from moving radially outwardly out of the slot as the arm 33 is turned, and to release the coin from the slotonly after it has been turned past the lower end 53 "of the shield 32.

Located directly below the lower end of the shield 52 asillustrated in Figure 10, is a hopper 54 leading into a coin chute 55. This hopper is provided with ears 53 by which it is secured to the plate 23 with screws I! or the like. The hopper is adapted .to receive the coin as it drops from the slot in the arm 33, and to guide the coin into the coin chute 5|.

Mounted on the coin chute 55 is a lug 5| pivotally mounting a lever 59 which carries on its lower end a coin catch 60 by which the coin is temporarily arrested in its movement downwardly through the chute 55. The point at which the coin is arrested is such that it will be directly in alignment with the window II in the front wall of the housing (see Figures 1, 2 and 4), and since the coin chute is also on that side as illustrated, it may be viewed from outside the housing. By this manner, counterfeits and slugs may be easily detected.

The lever 59 (see Figures 1, 10, and 11) is normally urged into such position that the coin catch will arrest the movement of a coin by means of a spring 8|. An oil-set portion 62 is provided above the pivotal support for this lever, and the upper end of the lever passes through a slot formed in a guide member I3. This upper end is beveled at N. When a coin is in position in the arm 33, and this arm is rotated as just described, the pin 44 on the channel shaped member 42 is adapted to engage the upper end of the lever 59 and move the coin catch out of position to release the coin that may be at the time held thereby. When the pin 44 passes the lever 59, the lever will resume its original position as shown in Fig. 10 so as to arrest the coin dropping from the arm 33. The arm 33 upon its return movement will not contact the lever 59 because of the fact that the pin 44 and the channel shaped member 42 will not be projected sufllciently without any coin in place in the arm 33 (see Figure 11) When the catch is released, the coin is moved downwardly from before the window II and the opening 65 in the coin chute and drops (see Figures 1 and 4) into the hopper 61 on top of the coin box 68. This coin box is resiliently held in its position by a leaf spring grippin device 69 in such a position that it is readily visible through the opening I2 in the front wall of the housing, and the opening 20 in the door I8, both of which openings have been previously described. The top of the box 08 is provided with an opening adapted to be closed by a sliding member I2 having an upturned end 13. The box 08 is provided with a downwardly turned. lip adjacent the upturned end of the slide, in such position. that when the slide is closed a seal I4 may be placed around its up-turned end and the downwardly turned ear on the box to seal the box shut.

When the arm 33 is rotated as previously described with the coin in position in its slot, the pin 43 (see Figures 4, 5, 6, and 11) will be moved to such a. position that it will engage the lever I5 mounted on a shaft I6, and secured in place by a nut 11. The shaft 16 is co-axial with the knob 9, and through the medium of the lever I5is rotated when the arm 33 is rotated with a coin in position. Mounted on the shaft I6 is a pinion adapted to engage a rack gear segment I8 (see Figures 8 and 9) carried by a pointer arm 19 (see also Figure 3). This pointer arm 19 is pivoted on a screw 80 and has an angled end 8I to which a cross member 82 is secured. This cross member 82 is bent at its ends and is formed with pointers 83 and 84 which are respectively adapted to movement over the dials 26 and 29 previously described. It will be here noted that these dials are graduated preferably in minutes of time (see Figures 1, 2, 14, and 16) and that the pointers are adapted to move over them as time progresses while the meter is in use.

A second arm 85 (see Figures 3, 8, and 9) is pivoted on the same screw 80 and provided with an oil-set portion 86 enabling it to follow the movement of the pointer arm I9 without interfering with the pinion onthe shaft I8. This arm 85 is provided with a bent end to which is secured a cross member 81 carrying shields or flags 88 and 89. The arm 85-extends in the opposite direction from the pivot 80 as shown at 90, and is provided with a notch 9I at its extremity adapted to coact with the end 92 of the pawl 93. When the pawl 93 is in engagement with this notch 9I, the shields 88 and 89 will be held in their lower position as illustrated in Fig. 9. The pawl 93 is pivoted at 94, and is provided with a spring 95 anchored on the plate 25 at 98 for the purpose of constantly urging the pawl into engagement with the notch SL The arm 85 is provided with a pin 91 on the extension (see also Figure 2), this pin extending through a slot 98 in the plate 25, and being connected on the opposite side of said plate with a spring 99. This spring constantly urges the shield arm 85 in such a direction as to move the shields upwardly over the dials 20 and 29 The pointer arm 191s likewise provided with an extension on the opposite side of the pivot 80, and this extension is such as to move. along the inner side of the pawl 93 (see Figure 9) without actuating this pawl until it contacts with an angled portion I00, as shown in Figure 8, formed on the inner side of the pawl. When this point is reached, further movement of the pointer arm 19 causes the pawl 93 to be moved out of engagement with the notch 9I-, and releases the shield arm so that the shields 88 and 89 may be moved upwardly by the spring 99 until they cover a substantial portion of the dials 26 and 29. l

The pinion on the shaft 16, which pinion bears the numeral IOI (see Figures 11 and 12), is located on one side of the plate 25. passes through the plates 25 and 30, and is pro vided on its opposite end with an enlarged portion I02, and a reduced portion passing through the plate 32. It is held in position within the plate 32 by means such as a nut I03. Surrounding the enlarged portion I02 is a main spring I04 secured at its inner end to the enlarged portion by means of a lug I05 formed thereon, and anchored at its outer end on a. pin I06 mounted on the plate 32. On the opposite side of the enlarged portion from the plate 32 (see also Figure 13) there is freely mounted a ratchet wheel I01 having ratchet teeth I08. Frictionally pressed against this ratchet wheel I0! is a friction disc I09. Against the opposite face of the disc I09 is one ofa pair of friction springs I I0 which engage each other. The other of these springs I I0 bears against the friction disc II I, and the friction disc III is held in position by means of an adjusting nut H2 and a lock nut II3 threaded on the portion II4 of the shaft I6.

Rotatable with respect to the ratchet wheel I01 (see Figures 11 and 12m a gear II 5 which is normally pressed against this ratchet wheel by means of a spring IIG bearilfgl against the edge of the main spring I04. This gear II5 carries a pawl I I1 pivotally secured thereto at II 8, and adapted to engage the teeth I08 of the ratchet wheel I0'I so as to permit relative rotation of the ratchet wheel and gear in one direction only. The gear II5 has teeth II9 meshing with a pinion I20 which forms a part of .a clock work gear train. This gear train includes a gear I 2I (see Figure 2) mounted on the same shaft with the pinion I20, and among others the gear I22 which serves to drive an escapement including the balance wheel I23. A customary lever I24 is employed for regulating the rate of escapement through the medium of the hair spring I25.

The operation of the meter just described is as follows:

A coin is inserted through the slot I0 and enters the slot 40 in the arm 33. The knob 9 is then turned and as it turns the coin 4I contacting with the beveled end 50 of the track 49 rides up thereon and causes the pin 43.,to contact the lever 15.

As the knob is continued to be turned, the lever 15 is turned together with the shaft 16, and the pinion IOI. This causes the winding of the main spring I04, the ratchet wheel I01 at this time turning within the gear H5 in the direction permitted by the pawl II I. If the knob be released prior to the completion of its turning movement, the arm 33 will be held against backward movement by means of the engagement between the coin H and the teeth or projections 5|. As the knob 9 is rotated further, the rotation of the This shaftpinion Ill serves to move the pointer arm II toward the position where the pointers l8 and 94 will indicate the zero point or the dials 29 and 29. As the pointers move downwardly they carry with them the shields 88 and I9, and when the lowermost point is reached, the shield arm is retained in this position by co-action of the pawl 93 with the notched end 9| oi. the shield arm. When the knob has been turned suiliciently for the coin to reach the lower end of the shield 52, the coin will drop from the arm 33 into the hopper 54, and slide down the coin chute 55 until it is stopped by the catch 60. It will be retained in this position so that it may be inspected from without through the window ll until the knob 9 is again operated with a coin in position in the arm 33. The first coin will then be released-by contact 01' the pin 44 with the lever 59, and will move downwardly again and drop into the coin box 68. When the knob 9 is released, after having been moved to its downward position, it will be returned by the spring 35 to its original position.

It will be seen that the movement 01' the knob 9 with a coin in position serves to rewind the main spring, to reset the pointer and the shields, and to start the clock mechanism measuring time. Rotation of the knob 9 without a coin in position, however, will cause none of these things, because the pins 43 and 44 will not project sumciently to contact with their respective levers l5 and 59. When the mechanism has been reset, the clock work will cause the pointers to move upwardly along the dials 26 and 29 until the position has been reached at which the pointers will indicate that the parking time paid for has expired. At this point, the extensioi of the pointer arm will contact with the pawl 93 and release the shield arm, thus permitting the shields to move upwardly over the dials and indicate that the parking time has expired, and if a vehicle remains parked ther after it is illegally parked. This is shown by t e signal shields, the particular length of time of overtime of parking being indicated by the further movement of the pointers along the exposed portions 01' dials 26 and 29. When the pointers reach the upper limit of their travel, the clock mechanism will automatically stop, and the meter will remain inactive until another coin is inserted and the knob 9 turned to reset the mechanism.

In order to prevent the insertion oi. a second coin and the turning of the knob part way to a position where it will be retained by the projections 5|, and cause the stoppage of the clock I mechanism without the shields moving over the dial, the knob 9 may be formed with an arrowshaped projection I26 so that an oflicer may readily observe if the knob is left out of its proper position. Both the arrow I28 and the shields 98 and 89 are preferably painted a distinctive color, usually red, so that a casual observer will have his attention attracted thereto.

It will be appreciated that by the structure above described there is provided a device capable of carrying out all the objects of this invention in a thoroughly practical and desirable manner. It will be appreciated, however, that various changes may be made in the parts and combinations thereof without departing irorn the spirit and scope of this invention as defined by the appended claims.
